Rhombus ABCD has vertices at A(-2,7), B(8,7), C(2,-1), and D(-8-1). Determine the area of ABCD.

Given a normal distribution with µ =50 and σ =4, what is the probability that 5% of the values are less than what x values? between what two x values (symmetrically distributed around the mean) are 95 % of the values? instructions: show all your work as to how you have reached your answer. don’t simply state the results. show graphs where necessary.
